Fortigate 5.4.9 Routing Issue

Dear ALL,

I have a question about the Routing Issue.Routing issues were detected yesterday afternoon in a firewall running on version 5.4.9 of the FortiOS.Due to current routing issues, there were no service issues, but management access was not possible with each firewall.

[Issue information]- management access was not possible with each firewall.- As a result of packet capture at the firewall, the SYN packet which tried GUI Access from the administrator's PC(192.168.120.15) was confirmed. However, the firewall does not export SYN + ACK packets.- We tested ICMP / SSH / HTTPS etc, but the result was the same.- The target of the "exec traceroute" command of the firewall has been specified as the administrator PC. However, the output value was identified as loopback ip with "127.0.0.1".e.g) exec trace route exec trace route 192.168.120.15traceroute to 192.168.120.15 (192.168.120.15), 32 hops max, 3 probe packets per hot, 84 byte packes1 127.0.0.1 <localhost> 2991.668 ms !H 3000.442 ms !H^C *
